Find the solution set of each of the following inequations in the given domain.
BARSIC [14]
<h3>Answer:  x ≥ 5</h3>

Since x is a natural number, this is the same as saying x > 4

=======================================================

Explanation:

Let's solve for x

x+12 < 4x-2\\\\12+2 < 4x-x\\\\14 < 3x\\\\3x > 14\\\\x > 14/3\\\\x > 4.667 \ \text{(approximate)}\\\\

Since x \in \mathbb{N}, this means x is a natural number and a value from the set {1,2,3,4,...} aka the set of positive whole numbers. Zero is not in the set of natural numbers.

So we'll need to round that 4.667 to the nearest whole number to get x ≥ 5

If we were to replace x with anything from the set {5, 6, 7, 8, ...}, then that would make the original inequality to be true.

The notation x ≥ 5 and x > 4 are identical when x is a natural number, because we're describing the same solution set of any whole number 5 or larger.

La edad de Alejandro equivale a las dos quintas partes de la edad de Andrea. Si la suma de
Mariana [72]

Las edades de Andrea y Alejandro son 40 y 16 años, respectivamente.

En esta pregunta debemos traducir el enunciado en ecuaciones algebraicas y resolver el sistema resultante. Tras una lectura cuidadosa tenemos el siguiente sistema de ecuaciones:

y = \frac{2}{5}\cdot x (1)

x + y = 56 (2)

Donde:

  • x - Edad de Andrea, en años.
  • y - Edad de Alejandro, en años.

A continuación, procedemos a resolver el sistema:

(1) en (2):

x + \frac{2}{5}\cdot x = 56

\frac{7}{5}\cdot x = 56

7\cdot x = 280

x = 40

Por (1):

y = \frac{2}{5}\cdot 40

y = 16

Las edades de Andrea y Alejandro son 40 y 16 años, respectivamente.
